A person will end up drier by running in the rain rather than walking.

Busted

The pair decides to wear coveralls through 2 to 3 inches (5.1 to 7.6 cm) per hour of artificial rain and compare walking and running weights to determine which absorbed more water (with bodysuits underneath to remove sweat absorption as a variable). The original test showed that running faster results in getting wetter, with wind only adding minimal amounts of water. The independent tests of Thomas Peterson and Trevor Wallace of the National Climatic Data Center disagreed, finding the runner 40% less wet. The result of this myth was overturned in MythBusters Revisited.

For the initial test at the Stoke Gas & Memorabilia Town in Santa Rosa, Jamie and Adam rigged a cell phone inside a Lexan blast chamber that would be filled with flammable fuel vapor. Also inside, to test a secondary theory—static electricity—they came up with a "panty-static generator" that rubbed a pair of panties on a fur-covered car seat (simulating a woman getting into and out of a car—something they decided on since they did a stakeout and found women are six times more likely to re-enter their cars while refueling) and transferred the static electricity to a Leyden jar.

However, the first test was a failure on both counts, so the two of them scaled back down to find the right mixture. It was during one of these tests that confirmed that static electricity combined with a potent fuel-air mixture could cause an explosion that Adam singed off his eyebrow—and, according to Jamie, a chunk of his hair.

With renewed vigor and knowledge of proper fuel-air mixtures, they returned to the Stoke Gas Museum, but found that neither the cell phone nor the panty-static generator caused explosions even with large amounts of the ideal fuel-air mixture inside the chamber, thus busting the myth. They did finally get an explosion when they added a neon transformer to the chamber, which blew the chamber into two halves and left the car seat on fire (Adam and Jamie had wired the chamber with a fail point so that it would be a safe failure and not cause shrapnel in case of a large explosion).

Using a hypobaric chamber, the implants expanded negligibly at 35,000 feet (11,000 m), an altitude too high for a human to survive for long periods. Using a hyperbaric chamber yielded no impact. A study by Duke University concluded that atmospheric conditions would be lethal long before they could affect implants. A spinoff of this myth was tested in Myths Revisited, while the DVD version includes second version of the spinoff.

It was proven that a high rotation (in excess of 23,000 RPM) could shatter the CDs, but the MythBusters could not achieve this using an unaltered drive. Physically damaged and unbalanced CDs made shattering more likely. The MythBusters concluded that while this event was possible, it was very unlikely to happen.

A bricklayer hoisting a wooden barrel full of bricks with a pulley from the top of a three-story building could be injured repeatedly.

Plausible

The MythBusters were able to injure Buster by hitting him with the descending barrel as it pulled him up, but the barrel would not break and spill its load until deliberately weakened by removing hoops and dropping it on a sharp edge. This allowed Buster's weight to overcome the broken barrel and fall, while a quick-release mechanism in Buster's hand holding the rope allowed the barrel to be dropped a second time for the third impact. But there was no evidence of the myth happening; the source of the myth appears to be a joke book. This test marks the first time Buster was broken in the course of an experiment.

Since ballistic gelatin has the same electrical resistance as a human body, the MythBusters rigged a dummy with a urination valve and electric release that would trigger with exposure to current. Even wetting the feet and removing shoes failed to trigger the release, due to the urine stream failing to stay laminar and solid enough to complete a circuit. A larger valve failed to create a solid stream, but setting the dummy unrealistically close to the rail finally succeeded. A spinoff of this myth was tested in Myths Revisited. In this episode, the "genitalia" region of the dummy is censored, and no reference is made verbally, instead referring only to the urination process.

While testing the myth at a train yard, the yard's operators gave Adam permission to test a "mini-myth" with one of their engines:

Notes

Placing a coin on a train track is sufficient to derail a train.

Busted

Adam placed four different types of coin on the track at the same time, but none of them had any noticeable effect on the engine. All that happened was that the coins were flattened and partially melted by the intense friction generated as the engine passed over them.

Most eel-skin wallets are not made from electric eels, but rather from a fish called a hagfish which does not produce an electric charge. Data written to a set of test cards were not affected in any way from this leather exposure, nor by direct exposure to an eel in a tank. In addition, further tests were conducted to see how much magnetism would it take to 'wipe' a card, and was found to be about 1,000 gauss(0.1T), far above what the average person may encounter.

A penny dropped from a skyscraper lands with enough force to either kill a pedestrian on the sidewalk below or embed itself into the sidewalk.

Busted

Firing a penny at terminal velocity (65 miles per hour (105 km/h)) into concrete and asphalt disks and a ballistics gel head with a human skull failed to result in any penetrations, likely because the speed is too low and a penny's mass too small. Even when fired from a rifle, the penny was unable to penetrate concrete or a ballistic gel dummy's skull. Even modifying a rifle to shoot a penny at supersonic speeds failed to cause a penetration. In comparison, a real 6.5mm bullet split the dummy skull. Visiting the Empire State Building, the likely source of the myth, they realize that updrafts and roofs of lower floors would prevent a thrown penny from reaching street level.

Despite mid-episode teasers, the MythBusters refused to microwave a live poodle, and were thus unable to test the myth that a microwave can dry a wet dog.

Notes

It is possible to cook one's insides by using a tanning bed too often, in a manner similar to how a microwave works.

Busted

Tanning booths work on ultraviolet radiation, which penetrates the body from the outside in, meaning that all one would get is a sunburn. They also demonstrated that microwave ovens do not cook food from the inside out.

Neither a spoon nor a fork had any effect. Tinfoil scrunched into balls caused a light-show with electric charges, but the microwave did not explode. Microwaving metal can possibly ruin a microwave by arcing against the inner wall, sending electricity back to the magnetron, and either destroying it or shortening its lifespan.

If a microwaved glass of water has an additive placed in it, it can explode due to superheating.

Confirmed (with limit)

If the water had no impurities in it at the time of superheating (like distilled water), then any sort of additive placed within will make the water flash to steam and violently spray. However, this will not happen with water from common sources (like tap water).

It is possible to build a super-microwave by aligning four magnetrons around a metal box.

Busted (unofficially)

If there is a proper method to build one, the method used in the show is not it. After a glass of water was exposed to the "super microwave"'s magnetrons for thirty seconds, a thermometer found that the temperature of the water had actually dropped by two degrees Fahrenheit(1.1 °C).

Jamie risked his own life for this myth, staying in the unburied coffin for 50 minutes; he maintained just 30 minutes when the soil was loaded above the casket. Suffocation from the lack of outside air or lethal poisoning from increasing levels of carbon dioxide would have claimed the life of anyone buried alive. Also the coffin (and occupant) could possibly be crushed by the weight of the soil pressing down on it. The risk of sudden collapse was the main reason the test was aborted after only 30 minutes. After the coffin was uncovered, it was found to have buckled significantly.

Adam and Jamie designed a fake car collision scene and used animal blood. After two hours, Adam used soap and water in one area while Jamie used cola in another. After rinsing both areas off, they noted while the cola wasn't really as effective, Jamie's area was cleaner than Adam's, leaving the myth confirmed.

Adam and Jamie proceeded to clean a dirty chrome car bumper. Adam used a leading commercial chrome polisher on one side, while Jamie used cola and aluminum foil on the other. In comparison, the cola side was surprisingly much cleaner than the chrome polisher side.

...loosen rusty bolts.

Busted

Adam soaked a rag in cola and then left it on the rusty bolt for 5 minutes. Adam tried to unscrew the bolt, but to no avail. Jamie managed to free it, but said it was very difficult and that the cola didn't really help.

Adam and Jamie placed a penny in cola and another in pure phosphoric acid, an ingredient used in cola but in low amounts. After 24 hours, the pennies were removed. The penny that was in the cola was considerably shinier, except for a spot where an air bubble had formed. Surprisingly, the penny that was in the phosphoric acid wasn't as shiny.

Adam and Jamie placed a tooth in cola and another in pure phosphoric acid. After 24 hours, the teeth were removed. The tooth that was in the cola was merely stained brown, while the tooth that was in the phosphoric acid had been dissolved to half its original size.

Adam and Jamie placed a steak in cola and another in pure phosphoric acid. After 48 hours, the steaks were removed. The steak that was in the phosphoric acid had been reduced to little chunks, whereas the steak that was in the cola had been tenderized but not dissolved.

...clean battery terminals.

Confirmed

Adam cleaned one car battery with baking soda while Jamie cleaned another with cola. Both were effective in removing the debris and rust, but Adam then cleaned a terminal with plain water. He pointed out that the only reason the cola may have worked was because it was a liquid, and not because of its properties.

Adam and Jamie dirtied their jumpsuits in car grease. After cutting a piece of fabric from each jumpsuit, Adam soaked his in a commercial detergent, and Jamie soaked his in cola. After four days of soaking, they rinsed the pieces and noticed that neither did a good job at removing the stains, and that the cola turned the material brown.

...degrease engines.

Busted

Adam and Jamie poured cola onto a dirty engine and let it sit for 10 minutes before rinsing it. While they noted that most of the dirt and rust had been successfully removed, most of the grease remained on the engine.

...ruin car paint.

Busted

Adam and Jamie applied cola to one section of a car and phosphoric acid onto another. After letting it sit for 24 hours, they rinsed the areas. The area with the cola had not been affected, but the area with the phosphoric acid was considerably whiter and thinner.

...kill sperm.

Busted

The MythBusters added cola to some slides and saline solution to others, then counted the number of live sperm they could see through a microscope camera in one minute. The number of live sperm in both saline and cola was relatively the same; and with the help of Dr. Turek, they determined that cola does not do much more than dilute the sperm.

...clean a bathroom.

Busted

Shown only in MythBusters Outtakes, Adam rubbed engine grease over surfaces in the M5 bathroom (much to Jamie's disgust). After successfully cleaning it with a commercial bathroom cleaner, he greased the bathroom again and had Jamie try to clean it with cola. The cola did not work at all, and Jamie forced Adam to clean the bathroom with the bathroom cleaner.

Dropping Buster with an internal accelerometer from a crane led to difficulty because the dummy continually lost parts on each control impact. Eventually, they managed consistent drops (mostly just below 300 g), finding that the hammer reduced the impact slightly, but the 150-foot (46 m) fall would still be lethal.

The lightning did seem to strike the dummy with a piercing more, but not the piercings directly. It would take a piercing the size of a doorknob to attract lightning. Given that the realistic piercings did not get struck, the myth was technically busted. Adam was also shown having his tongue pierced, but he did not keep the piercing after the test was concluded.

Under siege from a neighboring clan, a MedievalHungarian town (Paks) built a cannon out of a tree overnight, but wiped out a great deal of itself when the cannon exploded during a test-fire.

Plausible

It is impossible to bore a barrel out of a log in a single night using the technology available at that time, and Adam eventually used a chainsaw and electric drill. The cannon made of a log, loaded with 6 ounces (170 g) of period-realistic gunpowder, successfully fired a 1-pound (450 g) hand-chiseled granite cannonball a huge distance (exact measurement unknown since the cannonball was never found, even after 9 years). It also successfully fired a tennis ball, though a soda can merely leaked and contaminated the gunpowder. Loaded with 5 pounds (2.3 kg) of gunpowder, and with its barrel plugged, the tree cannon exploded violently enough to feasibly destroy part of a small medieval town. Since the testing of this myth, Jamie still looks for the cannonball in the bushes around the runway every time he does a myth on the runway.

A BACtrack B70 breathalyzer was used to test Adam's and Jamie's blood alcohol levels to ensure they were intoxicated. They then experimented to see if it is possible to pass a field sobriety test despite being over the limit, by...

Notes

...eating breath mints.

Busted

Adam's blood alcohol content only dropped slightly by an amount that was in the testing machine's margin of error. The only way this is likely to help is by masking the scent of the alcohol in the hope that an officer will not carry out the sobriety test to begin with, and even then it was pointed out that most tests are done either in response to erratic driving or at sobriety checkpoints, meaning that this would do nothing to prevent the test being performed.

...eating an onion.

Busted

Like Adam, Jamie experienced a blood alcohol content drop that was within the margin of error, and not enough to make it appear that he was under the limit. The scent of the onion was also so overwhelming that anyone using this tactic would likely get caught immediately.

...holding a battery in one's mouth during the test.

Busted

The battery had no effect whatsoever on the testing machine. The attending officer also noted that even if such a tactic worked, it would be extremely obvious and not likely to fool whoever was conducting the test.

...holding copper coins in one's mouth during the test.

Busted

Though less obvious than the battery, the coins also had no appreciable effect on the result.

...applying denture cream before the test.

Busted

Adam's test actually indicated a higher blood alcohol level than his original test; while the increase was in the machine's margin of error, the method was a clear failure.

On his initial test, Adam's blood alcohol level was indicated to be at near-lethal levels. When he tried again however, the reading came back only slightly elevated over his initial result. Even if a driver were able to use this method to generate a pair of clearly impossible results, which could throw doubt on the testing machine's accuracy, that driver would then be required to immediately submit to a blood test which cannot be fooled in any way and would definitively prove the driver's true blood alcohol level.

Inspired by a story of an attractive sports car being available at a very low price, but with a catch: someone had died in the car, and even despite cleaning attempts, the smell had persisted, meaning that the owner was finding it very tough to sell the car. To test this, Jamie and Adam procured a 1987 Chevrolet Corvette and placed two fresh pig corpses in it, which was sealed with tape and placed in a shipping container for two months.

If a decomposing body is left in a car long enough...

Notes

...the car's interior will be destroyed.

Confirmed

When unsealed, the car was full of condensation and maggots, and the upholstery was dirty and disintegrating. On further inspection it also turned out that the car's electrics (particularly the fusebox) had become severely corroded, rendering it unable to start. Furthermore, the decaying pigs gave off ammonia, which almost overcame Jamie when he sat in the front to steer the car out of the container.

...the car cannot be cleaned up enough to remove the smell completely.

Confirmed

For this segment, Jamie and Adam called in Neal Smither and the Crime Scene Cleaners, who regularly handle extreme cleanups, including the scenes of homicides, suicides and accidental deaths. He gave them tips on the process, including using a special bio-enzyme fluid to cut through the gunk and allowed them to practice on a coroner's van. However, though Neal believed that the myth was busted, he realized when he saw the car that it was indeed an extreme cleanup. The car was cleaned, but some parts (such as the seats) proved to be beyond the cleaners' abilities, as well as the impracticality of disassembling every part, and even Neal said it would take him and the Crime Scene Cleaners several days to get rid of all the smelly bits and reassemble the car as best as possible. Adam also reasoned that traces of material in the air conditioning system would cause the smell to linger.

...the car cannot be cleaned up enough to be sold.

Busted

After the smell and failure to start turned away several potential buyers, the MythBusters did find a buyer who was willing to purchase the car for US$2,000 and use it for spare parts (a scrapyard owner also offered $500, though the MythBusters rebuffed this offer as being too low).

A hillbilly was blasted 200 feet (61 m) out of a culvert when he tried to light gasoline in an attempt to chase down a raccoon which had escaped down the pipe.

Busted

To test this, Jamie and Adam procured a drainage pipe 3 feet (0.91 m) in diameter and placed Buster at the bottom before adding 5 US gallons (19 l) of gasoline. However, as they predicted, Buster was simply lit on fire when the gasoline was ignited - the reason being that there was a lot of space around him (no seal). To replicate the result, they encased Buster in a foam sabot, plugged the bottom end of the culvert and buried it and also used 10 pounds (4.5 kg) of black powder. Buster spectacularly exited the cannon but only traveled 100 feet (30 m), half the distance of their goal - and Adam also reasoned that no human would have survived a blast like that, let alone a blast powerful enough to launch all the way.

The inmates' intended destination after escaping Alcatraz was Angel Island. The MythBusters theorized that the escapees used the tides to go to a different location. The makeshift raft crafted and crewed by the MythBusters team successfully made it across the bay and made it to the Marin Headlands. They declared it "Plausible" because the fate of the prisoners remains unknown. A portion of the scale tests (cut for time but later shown in MythBusters Outtakes) also shows that belongings of the prisoners' found in the bay afterwards could have been released by the prisoners and washed up where they were found through strategic use of the Bay's tides to throw the authorities off their trail. The MythBusters explored the idea that the escape raft washed ashore on Angel Island after making it to the Marin Headlands as a way to throw the FBI off the convicts' trail. Using a scale model of the San Francisco Bay area, the tide could have washed the raft onto Angel Island if released from the Marin Headlands, but as with their theory of how the escape could have succeeded, no concrete evidence existed to prove or disprove the theory.

Jamie said that this was one myth they just had to test, since it is probably the most famous myth of San Francisco, where the show is based.

Initially unable to get either duck to quack, they began chattering when paired. Initially, no echo could be found, so the team moved to an anechoic chamber for comparison. When examined by an audio expert, it was found that the echo was "swallowed" by the original quack, due to the very similar acoustic structure between the quack and the echo. Because of this, it may be difficult to tell where the quack ends and the echo begins, both having similar waveforms on an oscilloscope and blending together in a way that makes them difficult to distinguish. In the same way, human hearing may not perceive the difference between a duck's quack and its echo.
